3 Claims. 1

The invention relates to cash registers, accounting machines or the like business machines capable of-selectively issuing a single check or a double check.

The check dispensing apparatus of the known machines of this type either issue a single check of the same length as the double check, or they issue a single check of half the length of the double check. Apparatus of the latter kind reduce the check tape consumption to one half when issuing single checks.

Experience has shown that the double check also may be kept shorter than customary because one portion of it, as a rule, is needed only for supervisory or auditing purposes. It is, therefore, an object of the invention to provide a selective check issuing business machine which, when set for the issuance of a double check, dispenses a check of shorter length than the known machines, thus further reducing the tape consumption and hence requiring a less frequent insertion of a new roll of check tape. Another object of the invention is to achieve the justmentioned improved performance -by simple and reliable means of minimum space requirements. An object of the invention is also to devise a machine that issues only a check of one kind, for instance only a single check, whenever the machine performs a predetermined operation such as the totalizing-of several additive amounts.

These and other objects and as well as the features of the invention will be apparent from the embodiments of the invention described in the following and shown on the drawing, in which:

Figure 1 shows a sectional side view of the printing and tape accommodating apparatus of the machine, and Fig. la a detail thereof;

Fig. 2 shows a plan view of the contro-l elements of the same machine;

Figs. 3 and 4 exemplify, respectively, a single check and a double check of the kind issued by the machine; and

Fig. 5 shows separately a side view of some of the parts of the machine.

According to Fig. l, a roll of check tape I is disposed on a shaft 2 in the upper part of the printing mechanism of a cash register or the like business machine. The check tape passes through a chute 3 along a paper guide 4 to the cutter 5.

The tape is advanced by a feeding device designed as follows. A drive shaft 6 carries two rubber cylinders 1 against which the check tape is pressed by contact edges or projections 8, 9, I0 of two transport cams II (Figs. 1, 2). In the illustrated embodiment the edges have substantially equalvperipheral lengths and are substantially equally spaced from one another. The cams II are rmly secured on a sleeve I2 journalled on a. shaft I3. Shaft I3 has eccentric extensions I4 journalled in a wall or frame structure I5.

An arm I1 is rmly clamped onto one of the eccentric extensions I4 (Fig, l). A pawl I8, plvoted on arm I 1, has two recesses I 9, 2U selectively engageable with a movable pin 2I and a stationary pin 22, respectively. The pawl I8 is linked by a connecting rod 23 to a cam arm 24. Arm 24 is secured to a control shaft 25 and has an angularly bent end 26 (Figs. la, 2) with a cam slot 21 (Fig. 2) engaged by a pin 28. Pin 28 is mounted on a bridge 29 which is displaceable but not revolvable on a shaft 39. The bridge 29 carries fork members 3|, 32 which straddle respective guide discs 33, 34'.

Guide disc 33 is firmly connected with two cams 35, 3S andris journalled on a shaft 31. Cams 35, 33 have a clutch member which in the illustrated position (Fig. 2) is engaged by a driving clutch member 38 of a, cam 39 pinned on the shaft 31 to revolve together with the shaft. Another cam 4i) similar to cam 39 is also pinned on shaft 31. The guide disc 34 is firmly connected with a cam 4I and revolvably mounted on the shaft 31. In the illustrated axial position of the displaceable cam 4I, this cam is engaged by a drive pin 42 mounted on a cam 43. C'am 43 and another cam 44 are rigidly secured on the shaft 31. Two rollers 45, 46 of a follower lever 41 ccact with respective cams 43, 44. Lever 41 is revolvably mounted on a shaft 48 (Figs. 1, 2) and has an extension 49 which carries a slide piece 59 (Fig. l) straddled by a bifurcated arm 5I. Arm 5I is secured to the revolvable cutter 5 for actuating the cutter. A stationary cutter plate 53 cooperates with cutter 5.

Two other cams 54, 55 (Fig. 2) are rigidly attached to the shaft 6 and cooperate with respective cam rollers 53, 51 of a follower lever 58 (Figs. 1, 2) pivoted about the shaft 48. The above-mentioned pin 2I is riveted to an extension of the lever 58 (Fig. l). Shafts 6 and 31 (Figs. 1, 2) are geared together by spur gears 59, 69, 6I. Two further spur gears 62, 63 transmit the tape transport movement. Gear 62, mounted on shaft E and thus connected with one of the rubber cylinders 1, meshes with the gear 63 mounted on the sleeve I2.

A shaft 64 (Fig. 1) carries a printing hammer 65 to cooperatewith the type wheels 65. The

`ginning 'of the machine operation,

3 printing hammer 65 has a back member 51 which cooperates with one or the other cam 35 and 35 (Figs. 1, 2) depending upon the adjustment of these cams along the axis of the cam shaft 37. A clich hammer 58 has two back members 69 to cooperate with cams 39 and di).

If a single check is to be' dispensed, the control parts areadjusted to zthe respective "positions shown in Fig. 1. In `these positions, vthe Arecess I9 of pawl I8 straddles the pin 2 I. At the beginning of the machine operation, the lever 58 is first turned counterclockwise (Fig. 1) dueto .the action of cams 54, 55. As a result,'pin2I of lever 58 causes pawl i9 to move ,the arm -I1 .counterclockwise (Fig. 1) about the extensions It of shaft I3. Thus, the sleeve i2 with tape transport cams I I is movedso that only the contact edges 9 and I0 of the transport cams II become effective to advance the check vtape during the course of the machine operation.

.During the dead interval, corresponding to the peripheral spacing between cam vedges 9 `and 9, .the amount-printing hammer -55 is actuated by cam 35., and the clichefprinting hammer l55 is actuated by cams 59, li. Prior to the advance Aof the check tape, .the cutter is turned clockwise (Fig. 1) b-y parts di, 69, 59, 5I to a position .in which its cutting edge is sufliciently spaced from that of the Vcutter plate 53 to permit the `freepassage of the check tape. After the printof the check tape, the cutter thus cutting the .ing .and vadvancing :Bfr-eturns to its original position,

printed check from the tape.

.If a double check yis to be dispensed, the control shaft is turned, for instance under con- :trol by-'an operator-actuable key or button, so .that "the recess 20 of pawl I' moves over the stationary pin 22 (Fig. 11). The control shaft 25, bymeans of parts 24, 26,21, 28 causes a displacement of the bridge 29 :along shaft 30 (Fig. As a result the bifur'cated member 32 shifts disc -3-4 along shaft 3'I and thus places the cam Y'II into the operating range of the roller 46 of follower lever 41. Simultaneously, the bifurcated member 3'I shifts cam 33 and thus places the .cam into the range of the back member 61 of the amount-,printing hammer 55. At the bethe lever 58'is moved counterclockwise (Fig. 1.) Now, however, .this movement .has no effect .on .the-.pawl I2, because the pawl is vbeyond the range of movement of pin 2l. Consequently, during the machine ,operation-all contact edges 8, 9, and I9 of cams II `are now effectivevto advance the `check tape. IPrior to the advancing movement of the check tape, the amountto-be'registered is printed'under control by .cam 35 which is now located 'within the. range of the yback member 51 of printing hammer 65. Forxan interval of time after the first-contact edge 8 has advancedthe tape and bef-ore edge 9 engages the tapa'the tape remains .at rest. During `that intervaLthe yamount-fprintingl .hammer 55 and the :clich hammer 58 are .actuated to `print one portion ofthe check. 1mmediately. thereafter the-contactedge 9 advances the tape another step. Then the cutter 5 is turneda smaller ,angle than before to emboss or perforate a tear .line on .the tape. This occurs under contro-l by cam Illl which, as mentioned,

has been placed into .the vrange Iof the rollerAB-of the lever 'i. A.lveiiorethe next .contact edge -II) engages .the tape, |the cutter 5 is turned back to the open position under control by cam dit .so that the contact edge I9 can advance the check tane a further amount. Near the .end .of the axis ,of the eccentric with particular ref erence'to'jFig.; 5.

Thepawl I8 has an extension "I0 to cooperate with the pin II of a connecting rod 12. Rod 'I2 .is linked to a bell crank lever 'I3 pivoted on a shaft 18. `A Aroller I4 on level` 13 engages the cam slot "I5 of acam member 'i5 mounted on a .shaft 1.9. The angular position of shaft 'I9 is controlled Aby .the operation adjusting means or `control keys (not illustrated) of the machine. The connecting rod 23 has an elongated hole '11. Pawl I8 is resiliently connected with the connectingrod 23 of a spring 80.

If a total or subtotal is to be taken, shaft I9 and cam member 'I5 are turned clockwise. As -a result, the pin 'II mov-es .toward the kextension 'I9 of pawl I8 `and either retains it or `places-.it in the position shown by solid lines in Fig. 1. .As explained, only single checks are dispensed in this position of the pawl vI8 The pin 'II thus forms a displaceab-le stop which retains the pawl I8 in the adjustment for issuing a single check .whenever a total or subtotal-is taken, regardless of the angular position to which the control shaft 25 may then be set. That is, for instance, when shaft 25 is seit for issuance of a double check, the machine normally 'issues such checks but tis automatically controlled to issue a single check when a total is drawn.

After .a study of .this disclosure, it will `be obvious to those skilled in the art that, -as far as design anddeltails are concerned, the yinvention permits various modifications without .de- `parture from its essential features as vset forth in the claims annexed hereto.
